A UWin Account, also know as a UWin ID, username, login, account, user id and computer account, is the unique ID assigned to all students and most staff and faculty for computer access which is the segment of your University of Windsor email before the @uwindsor.ca part. For example, in the account firstname.lastname@example.org the "myname" segment represents the UWin Account.
Student and Instructors need to have a valid UWin Account (or ID) in order to access CLEW.
